Current Beach Water Advisories

Beach monitoring has ended. It will resume the week of May 20, 2019.

About public beach water testing

The Eastern Ontario Health Unit (EOHU) samples the swimming water at all local public beaches throughout the operating season to ensure it does not exceed the established bacteria levels. If bacteria levels exceed the safe swimming limit, a sign is posted advising people that the water is unsafe for swimming. Beaches are re-opened after bacteria levels return to acceptable levels.

Safe for Swimming: Bacteria level in the water poses no health risk.

Unsafe for Swimming: High levels of bacteria in these waters may pose serious health risks.

Closed: Beach closed. No Swimming.

Not Monitored: The beach is not monitored by the EOHU at this time.

The EOHU is not mandated to test the water quality of private beaches. Private beach operators are responsible for monitoring the bacteria levels of their water.

Why is a public beach posted?

An elevated bacteria density in the water is the major cause of postings. The most common bacteria is E. coli, which may indicate the presence of fecal coliforms (FC), an organism that exists in the feces of virtually all warm-blooded animals. In Ontario, the recreational water quality guideline is a maximum of 200 E. coli per 100 mL of water.

Occasionally, a public beach may also be posted if the inspector notices floating debris, oils, scum, excessive algae growth, bad odours and turbidity.

A public beach that has been posted because of high contamination levels will be subjected to more frequent water sampling.

What causes contamination?

Very little movement or flow in a body of water may create the right conditions for contamination. However, this water degradation is preventable.
